Detection of IgM Antibodies Directed Towards Chikungunya Virus by IFA

Serological detection of IgM antibodies directed towards Chikungunya virus using the Euroimmun anti-chikungunya virus indirect immunofluorescence test.

Serum. Minimum volume of  250 ul required.

Collect blood in serum separator tubes.

Store samples refrigerated or frozen until shipped for testing. Ship samples on a cold pack, or with wet or dry ice.

Shipping of specimens shall be done by a TDG certified individual in accordance with TDG regulations. For additional information regarding classification of specimens for the purposes of shipping, consult either Part 2 Appendix 3 of the TDG Regulations or section 3.6.2 of the IATA Dangerous Goods Regulations as applicable.

Suspected chikungunya virus infection and relevant travel history.

Completed Viral Zoonoses requisition including sender laboratory name, address and telephone number. Patient name and / or identifier (specimen reference number), date of birth, test(s) requested, collection date of specimen, date of on-set of symptoms, type of specimen, and clinical and travel history of patient.

N/A

1. The detection of chikungunya IgG antibody in a single sera is indicative of past or present exposure to this agent. The presence of chikungunya specific IgM in a single serum sample is consistent with an acute infection to this agent and meets the criteria for a "probable case". However, a 4 fold rise or greater in neutralizing antibody titre, or an IgG or IgM seroconversion in paired sera, is required to document a "confirmed case" of infection with associated illness.
